Application tiled December 2li, 1914.

vide a resilient armor between the inner pneumatic member and the outer casing; or treadinernber of a pneumatic tire so as to protect the inner pneumatic member from puncture, to provide an annular cushion between the inner member'and the tread-member or the pneumatic tire which coacts with tbe 'inner pneumatic member in cushioning' the tire, and to provide a cushion of novel construction for the tread-member.

The' invention Will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure' is a side elevation of my impartly broken away for better illustration of the parts.

Fig. 2 is a cross-section on the line 2--2 of Fig. l; and, f

ig. 3 is a perspective view of a section 'tbe armor.

ll represents the body of the vehiclevvlieel which may comprise the hub l2, spokes i3 and the telly 14.

The outer easing or tread-member of the tire is represented at 15. The inner member or pneumatic tube of the tire is represented at i6. "Within the casing there is a cusbionf member 17, shown interposed between the tread-member and inner tube of the tire.

the forni shown, the casing is held in place by means of annular flanges 2l, 22, Wbieh coact'with the annular bases 23, 24, of 'the casing. The annular flange 2l eX- tends integrally from an annular band 25 which is provided with an annular groove 26 in which an annular split-ring 27 is received.

The annular i'iange 22 is on an annular integral ring 23 Whichis held about the annular band 25 b v means of the split-ring 27.

'A usual annular apron 29 is received between tliebases of the casing and the inner tube for protecting the pneumatic tube of tbe-tire. The innery portion of the casing has fabric strips 30 embedded therein. The annular band 25 is suitably attached to the bodv of the vvbeel.4

'be cushion-member 17 is .termed eres# Specification of Letters Patent.

Patented dan Elli., serial no. aras/aa l cent-shaped in cross-section, with the horns 3l of the crescent projecting inwardly to- Ward each other, the inner ends "ci these horns'being supported by the inwardly sloping portions 32 of the casing when the pari-s are assembled. The horns gradually increase in cross-section toward the side portions of the cushion-member 17, as slioWn vat 33.

At each side oi the outer annular periph eral portion or" the cushion-member, it is provided with recesses 3i, which preferably extend annularly between the horns 3l and the base 35 or the cushion-member. This base is at the outer annular portion of the cushion-member. An inner web 36 of the cushion-member connects the base with each of the horns, and the inner portion of tlie cushion-member preferably has fabric strips 37, for instance, canvas, embedded therein for strengthening' the same and strengtbening the Webs 36. The cushion-member is preferably of resilient material, for instance, rubber. it the recesses 34, it is pro vided with laterally extending Wings 38, 39, formed in the body of the cusiiionmeniber and formingresilient Wings. The outer annulafr portion of the cushion-member is somewhat "l"sliaped in crosssection, tbe shank 40 enhancing the resilient properties of the cushion-member, the Wings 38 extending laterally at each side of said shank.

When the pressure of the load is exerted upon the cushion-member l?, the tendens is to partly compress the base 35, and to spread the cushion-member laterally, tbe resistance to the Weight of the load being' iurtber received upon the inwardly sloping portions 32 oi the casing.

The cushion-member 17 acts as a, protecting armor for tne inner tube.

My invention provides a pneumatic in which the inner tube is removed troni the casing of the tire by armor which forms a cushion-member for the tire, and protects the inner tube from puncture by penetration of foreign objects, and from blow-outs. rlhe outer annular portion of this armor is so formed as provide resiliency between the inner tube and the casing, and the armor is so :formed in cross-section as to receive support at its innerV portions upon the base portions 32 ot' tile casing, the armor being further pro vided with resilient Wings Wbiel aid in tbe .cushioning eli-ect The inner tribe an interposed resilient titl further acts to spread the armor and the casing so that the casing is firmly held in the usual detachable mountin for the outer casing or tread-member, one orm of which is shown in the drawings by the -flanges 21, 22. The outer recesses in the armor especially when annularly arranged serve as v cooling agents for the tire.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. Ina vehicle wheel, the combination of an annulaitire retainingmeans, a casing having portions coacting with said retaining means and extending toward 'each other, an annular iniatable pneumatic tube in said casing, and an annular cushioning armor interposed between said annular inflatable pneumatic tube vand casing substantially crescent-shaped in cross-section, the horns of the crescent extending toward each other and overlapped substantially by said pneumatic tube when iniated, and the said annular cushioning armor provided with outer annular-ly arranged recesses for forming said armor with a tread portion which is substantially T-shaped in cross-section and with webs which are outwardly curved in cross-section connecting the base of said T- shaped tread-portion with said horns, the

an annular casing having inner portions extending toward each other, an inner an-l nular inflatable pneumatic member, and an annular. cushion-member in saidcasing having an annularly arranged peripheral portion which is substantially T-shaped in cross-section for forming a resilient stem and resilient wings Whose outer ends extend integrally laterally from said stem, said annular cushioning member further having annularly arranged horns at its inner portions supported by, said inner portions of said casing and connected with said substantially T-shaped portion by means of resilient webs, and the said webs and said resilient wings being outwardly curved in cross-section for spreadingthe sides of said armor by pressure on said annularly ar- .ranged peripheral portion.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
